SPECIFICATION formingpart of Letters Patent No. 515,063, dated February 20, 1894.

Application led August 9, 1893. Serial ITol 482.771.. (No model.)

To all whom it may concern:

Be it known that we, JUsTUs A. TRAUT and CHRISTIAN BODMER, citizens of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to adj ustable-mouth planes, the object being to furnish means for adjusting the mouth-slide and for holding the same in place.

In the drawings accompanying and forming a part of this specification, Figure 1 is a plan View of. a portion of a plane furnished with our present improvements. Fig. 2 is a sectional side view of the plane. Figs. 3 and 4 are views similar to Figs. 1 and 2, respectively, for illustrating the mode of operation of the improvement. Fig. 5 is a view similar to Fig. 1, showing a modification of the improvement. Fig. 6 is a sectional side view of a portion of the same. Fig. 7 is a view similar to Fig. 1, showing anothermodication.

Similar characters designate like parts in all the figures.

Referring to Figs. 1, 2, 3 and 4, the letter B designates the forward portion of an ordinary iron smoothing-plane of the class which are usually provided with a mouth-slide, also sometimes designated as an adjustable front, for regulating the width of the mouth 2, of the plane. The usual plane-iron or cutter is shown in place at 3, held under the forward end of the ordinary clamp, 4, in a wellknown manner.

The mouth-slide designated by 5, is shown provided with a stud, 6, preferably rigidly xed therein as indicated in Figs. 2 and 4. Said stud 6 extends upward through the' forward end, 7, of the plane-frame, and is provided on its threaded upper end with a clamping nut, 8, whereby to hold the mouth-slide in place.

According to ourpresent improvements, the plane is furnished with a mouth-slide actuator, designated in a general way by D, and whose principal portion constitutes an adjustable block or thrust member, designated by 9, intermediate to some part of the mouthslide and a suitable fixed stop-abutment, as, for instance, the pin 10, on the plane-frame. In the preferred form thereof shown in Figs. l to 4 inclusive, said actuator consists,vessen tially, of an eccentric disk 9; this is shown provided with a loop or outer bar, 11, bearing against the opposite side of the aforesaid abutment-pin 10, as clearly shown in said tigures. By turning the actuator D toward the right-hand or left-hand, as for instance vfrom the position shown in Figs. 1 and 2 to that shown in Figs. 3 and 4, the mouth-slide will be moved, in the presentinstance toward the right-hand for widening the open space, 2', between said slide and the cutter 3, as will be seen by comparison of said iigures of the drawings. The actuator D, being set on the plane-frame underneath the clamp-nut 8, is thereby rigidly held in place when said nut is screwed down for holding the mouth-slide.

The actuator D is shown pivotally supported on the stud 6 of the mouth-slide 5, so that in connection with the actuator slot 12, and the abutment-pin 10, said actuator holds the mouth-slide positively against movement in either direction; said abutment-pin fitting closely but freely within said slot, and the forward and rearward sides of said pin constituting oppositely-disposed stop-abutments.

In Figs. 5 and 6 we have shown a modification of the invention, in which the actuator, here designated by D', consists of an eccentric disk 9 which fits on the clamp-screw 8', and works between the forward and rearward abutments 14 andl, of the plane-frame (see Fig. 6) so as to control the position of the mouth-slide in substantiallythe same manner as described in connection with Figs. l to 4 inclusive. Said disk 9 is shown furnished with a knurled rim 16, whereby the operator may conveniently turn the actuator for adjusting the mouth-slide.

In Fig. 7 there is shown a further modification of the improvement, in which the actuator D consists of a fiat lever 17, iitted over the stud 6, (this being the same as the one shown in Figs. 1 to 4 inclusive) and having a pin or stud, 18, fitting in an eccentric groove, 19, between the forward and rearward abutments 2O and 2l, formed on the plane-frame and corresponding to those shown in Figs. 5 and 6 and also (in reverse order) to the for- Ward and rearward sides of the abutment-pin l0 shown in Figs. l, 2, 3 and 4. In Fig. 7, the clamp-nut is omitted for the purpose of more clearly illustrating the other features; but it is or may be the same as the one shown in Figs. 2 and 4. In Figs. 5 and 6, the clampscrew 22 is shown formed integral with the head 8', and in Working engagement with the corresponding internal thread of the mouthslide, as will be understood from Fig. 6. y

Having thus described our invention, we claiml. In aplane, in combination, a plane-frame having a stop-abutment upon the upper face thereof, a mouth-slide having a Xed stem, vertical thereto, an independently operable mouth-slide actuator supported upon the upper face of the plane-frame and engaging the stem and stop-abutment so as to rotate about pose set forth.
